Application filed November 3,1915. Serial No. 59,375.

To all whom it may concern:

Be it known that 1, WILLIAM A. HoLMns, a citizen of the United States, residing at Parkplace, in the county of Clackamas, State of Oregon, have invented a new and useful-Envelop; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved envelop, designed to be employed as a merchandise carrying envelop, and which may be employed also as a sealed envelop Without any structural changes.

A further object of the invention is to provide an envelop having side and bottom flaps, so folded and so provided with adhesive material, that when the side and bottom flaps are sealed, a pocket is formed between the end of the bottom flaps and parts of the side flaps, for the reception of the closure flaps, which, if necessary, may be sealed.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

. In the drawings: Figure 1 is a view in perspective of the improved envelop constructed in accordance with the invention.

Fig. 2 is a plan view of the blank, fromwhich the envelop in Fig. 1 may be constructed. Fig. 3 is a perspective view of an envelop of a diiferentshape in plan view Fig. 1, showing the closure flap receiving pocket. Fig. 4 is a plan view of a blank from which the envelop in Fig. 3 may be constructed. Fig. 5 is a perspective view of an envelop showmg another form of envelop, but stillhaving a pocket for the reception of a closure flap, and provided with additional means for holding the closure flap closed. Fig. 6 is a plan view of the blank from which the envelop in Fig. '5 may be constructed.

Referring to the drawings, 1 designates the blank for forming the improved envelop, particularly that form shown in Fig. 1. The blank is provided with the side flaps 2 and 3, and the bottom flap 4, and the closure flap 5, which closure flap is constructed with a slot or recess 6. It is to be seen that the side, bottom and closure flaps are inte- 17, or if desired the tongues 19 may be sealed connected to the back or address porgrall of the envelop. The side flaps 2 and 3 tion fold upon the dotted lines 8, whereas the bot- I tom and closure flaps fold upon the dotted a0 lines 9 and 10. The upper portions of the side flaps 2 and'3 are constructed with extension tongues 11 and 12. The inner face of the bottom flap is provided with adhesive material 13 adjacent its side edges, whereby an the bottom flap may be sealed to the side flaps. However, before sealing the bottom flap, the side flaps are folded upon said lines 8, so that the extension tongue 12 (which is provided with adhesive material 14) may be 7e sealed to the extension tongue 11. The inner face of the closure flap near its end portion 15 is provided with adhesive material 16, which, when the bottom flap is folded upon its line 9, seals the bottom flap to the extension tongues 11 and 12, immediately over where said tongues 11 and 12 are sealed together. It is to be noted that by this method of sealing the bottom flap to the side flaps and their extension tongues that pockets 17 so are caused to be formed by the blank or nonadhesive surfaces 18. These pockets 17 are designed to receive the tongues 19 (which are caused to be formed by the provision of a slot or recess 6) of the closure flap 5, for closing the envelop, that is to say, when the envelop is designed to be utilized asa merchandise carrier, but if it is desired that the envelop is to be used as a sealed carrier for first class mail matter, the user may apply adhesive material to the inner faces of the tongues 19. In this case, however, the adhesive material should be moistened before inserting the tongues 19 in the pockets upon the outer portions of the bottom flap and the extension tongues 11 and 12. In Figs. 3 and 4 practically-the same principle of construction as used in Figs. 1 and 2 is employed, with the exception that the plan outline or shape or arrangement of the adhesive material 13*, is materially changed, therefore providing a single pocket 17, for the reception of the closure flap 5 The single pocket 17 is formed by the blank or non-adhesive space or surface 18*. Furthermore, in. Figs. 3 and 4 the general shape of the blank for forming the envelop in Figs. 3 and 4 is somewhat altered. In Figs. 5 and 6, the envelop is of the general outline as that 1 shown in Figs. 3 and 4, and is provided with a single pocket for the reception of the end stead of closed as shown. in Fig.4.

of the closure flap 5". However, the outline of the adhesive material 13 is changed so that the bottom of the pocket is open,

e pocket 17 in Fig. 5, which is formed by the construction of the blank in Fig. 6 receives the tongue 5 (which is provided with a transverse slot 20) after which the tongue 21 of the bottom flap may be inserted through the slot 20, thereby additionally holding the closure flap closed. If required or necessary the closure flaps in Figs. 3, 4, 5 and 6 may be sealed Within'or upon the outside of the POCkGtSyif it is desired that the envelop be used as a carrier-for first class mail matter, by the user applying adhesive material to said closure flaps.

The invention having been set forth, what is claimed as new and useful is In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
